Tom and I have worked for several weeks on a comprehensive draft of the sections delineating first parties and third parties. We attempted to reflect the approaching-consensus discussion at Santa Clara and on the email list. Our draft includes both operative standards language and non-normative explanation and examples. The text is formatted with the W3C template to better resemble how it would appear in the final document; please note that this is not an Editor's Draft (as the template might suggest).
